What does this error message mean After I try to save my file?

I am painting base colors on my object and when I go to Save As or Save I get this message;

Unable to pack file, source path… .png not found.

And it is referencing a file folder I am not using(3D Coat Files)

Blender is doing weird things to me lately. Lots of weird things. Probably me but I can’t figure it out.

If you’re not using those files then it’s safe to ignore. They have probably been moved or deleted at some point? You can just save normally and disregard the message.

If you were using them you’d need to point to their new location -

Thanks dan2
